Need help?3GPP to MPEG Converter
This page re-encodes a .3gpp clip — the small mobile container 3GPP specified in TS 26.244 for 3G-era handsets — into a .mpeg file, which is an MPEG program stream: the multiplexed audio-and-video format that Video CD, DVD-Video, and a generation of desktop editors and capture cards were built around. It is a conversion between two legacy formats, and worth doing when something on the receiving end genuinely expects MPEG.
If nothing does, the honest recommendation is MP4. It is smaller, plays natively on every current phone, browser and TV, and is on every upload allow-list — 3GPP to MP4 is that conversion. Read on if MPEG is what you actually need.
What a .mpeg File Actually Is
The .mpeg and .mpg extensions identify an MPEG program stream: elementary video and audio streams multiplexed into one file with the packet and timestamp structure defined in MPEG-1 Part 1 (ISO/IEC 11172-1) and MPEG-2 Part 1 Systems (ISO/IEC 13818-1, also published as ITU-T H.222.0). Program stream was designed for reasonably reliable storage such as discs and hard drives; its sibling, transport stream, is the loss-tolerant variant used for broadcast.
That means "MPEG" names a container plus a codec family rather than a single format, and a .mpeg file can hold MPEG-1 or MPEG-2 video. Our MPEG output is written as MPEG-2 video with MP2 audio unless you change it, which is the pairing DVD-era software and hardware expect.
MPEG-1 and MPEG-2 Compared
| Property | MPEG-1 | MPEG-2 |
|---|---|---|
| Standard | ISO/IEC 11172, published 1993 | ISO/IEC 13818 | ITU-T H.222.0/H.262 |
| Design target | Around 1.5 Mbit/s combined audio and video, CD-ROM speed | Roughly 1.5 to 15 Mbit/s and beyond, broadcast and disc |
| Scanning | Progressive frames only | Progressive and interlaced |
| Typical resolutions | 352×240 and 352×288 (Video CD) | 720×480 and 720×576 (DVD), plus HD profiles |
| Usual audio partner | MPEG-1 Audio Layer II (MP2) | MP2, AC-3 or PCM |
| Patent position | Long expired | The last US patent covering MPEG-2 video expired in February 2018 |
| Where you still meet it | Video CDs, old capture files | DVD-Video authoring, DVB broadcast, archives |
How to Convert 3GPP to MPEG
- Upload Your 3GPP File: Drag the
.3gppclip onto the page or click "+ Add Files". Old feature-phone recordings, MMS attachments and early-smartphone captures all work, and several files can be queued for one batch. - Choose the Video Codec and Audio Codec: The output is written as MPEG-2 video with MP2 audio by default. The Video Codec list also carries MPEG-1 if a genuinely old player needs it, and the Audio Codec list offers MP2, MP3, AC3 and PCM among others.
- Set the Quality Preset, Resolution and Trim: File Compression starts on the "Very High (Recommended)" Quality Preset, with "Target file size (%)", "Specific file size", Constant Bitrate and Variable Bitrate beside it. Under Video resolution, "Keep original" respects the source — a 3GPP clip is usually 176×144 or 320×240, so there is nothing to gain from a DVD-sized preset — and Trim → Time Range cuts the clip down first.
- Convert and Download: Click "Convert" and save the
.mpeg. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared or made public.
3GPP Source vs MPEG Output
| Property | 3GPP (.3gpp / .3gp) |
MPEG (.mpeg / .mpg) |
|---|---|---|
| Container defined by | 3GPP TS 26.244, profiling ISO/IEC 14496-12 | MPEG program stream, ISO/IEC 11172-1 and 13818-1 |
| Video codec | H.263, MPEG-4 Part 2, sometimes H.264 | MPEG-1 or MPEG-2 video |
| Audio codec | AMR-NB, AMR-WB or AAC | MP2 by default; AC3, MP3 or PCM available |
| Typical bitrate | Tens to a few hundred kbit/s | Low megabits per second |
| Designed for | 3G cellular transfer at minimum size | Discs, broadcast and desktop editing |
| Media type | video/3gpp |
video/mpeg |
| Status today | Legacy; phones moved to MP4 | Legacy but still required by DVD and DVB workflows |
When MPEG Is the Right Target
- You are authoring a DVD. DVD-Video is an MPEG-2 specification; authoring software will reject an MP4 and accept a program stream.
- A broadcast or capture chain asks for it. DVB ingest and older studio kit still specify MPEG-2 video.
- You are feeding vintage editing software. Editors from the DVD era open program streams natively and often cannot import modern containers.
- Patents matter to your distribution. MPEG-1 and MPEG-2 are past their patent terms in essentially every market, which is not true of newer codecs.
Frequently Asked Questions
Does converting 3GPP to MPEG make the video look better?
No. The clip was captured at a cellular bitrate at 176×144 or 320×240, and that is the ceiling on detail forever after; re-encoding to MPEG-2 adds a lossy generation rather than removing one. Choosing a DVD-sized preset under Video resolution does not sharpen anything — it enlarges soft pixels. Leave the resolution alone and let the player scale.
What happens to the AMR audio inside my 3GPP file?
It is re-encoded. AMR is a 3GPP speech codec with no place in an MPEG program stream, so the audio is converted — to MP2 by default, the Layer II codec the MPEG world standardised on. Intelligibility is preserved, but AMR-NB sampled at 8 kHz across roughly the telephone speech band at 4.75–12.2 kbit/s, and nothing can add back frequencies the handset never recorded. Clips that stored AAC instead of AMR keep more of their original range.
Why is the MPEG file so much larger than the 3GPP was?
Because the two formats were designed for opposite constraints. 3GPP squeezed video down to fit 3G cellular links; MPEG-2 was engineered for disc and broadcast bitrates in the megabits per second, and even its efficient settings sit well above what a feature phone used. Expect growth, and manage it with a lower Quality Preset, "Target file size (%)" or "Specific file size", or by shrinking the result afterwards with the video compressor.
Should the output be MPEG-1 or MPEG-2?
MPEG-2 for anything modern that still speaks MPEG — DVD authoring, DVB, capture-card software — which is why it is what we write by default. MPEG-1 only when you are targeting Video CD or a player old enough to predate MPEG-2, since MPEG-2 decoders read MPEG-1 streams but not the other way round. MPEG-1 is also progressive-only, which is irrelevant for a phone clip that was progressive to begin with.
Is .mpeg the same as .mpg?
Yes — two extensions for the same MPEG program stream, one truncated for the old DOS-era three-character limit. Some applications prefer one spelling, so if a program refuses the file it is worth renaming rather than reconverting. Neither extension tells you whether the video inside is MPEG-1 or MPEG-2; only the stream does.
Can I go the other way and get a modern file back out of an MPEG?
Yes, though it is another lossy generation: MPEG to MP4 re-encodes a program stream into MP4, which is the sensible move once a DVD-era file needs to play on a phone or in a browser. If you have both the original .3gpp and the .mpeg, convert from the .3gpp — every re-encode from a re-encode compounds the losses.
My file is called .3gp rather than .3gpp — does that matter?
Not to the footage; they are two extensions for the same 3GPP container, and .3g2 is the closely related 3GPP2 format from CDMA2000 handsets. It matters to the uploader: this page takes .3gpp, and 3GP to MPEG takes .3gp and .3g2 with the same options.
How are my files handled during conversion?
They are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and nothing is shared or made public — only the .mpeg you download leaves the process, and the original clip on your device is untouched.
